SPECIFICATION forming part of Letters, Patent No. 506,538, dated October 10, 1898.

Application filed duly 24,1891, Serial No. 400,697. (No model.) i

To all whom-it may concern:

Be it known that I, LANSING ONDERnoNK, a citizen of the United States, residing at Uhicago, in the county of Cook and State oi lllinois, have invented certain new and useful Improvements in Sewing-Machines; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use' the same.

' My invention relates to sewing machines of that class having a plurality of needles arranged to sew simultaneously several parallel rows of stitches. I

The present invention relates particularly to a machine when the needles are arranged in sets, one at least of said sets having a plurality of needles, the sets being arranged di- A agonally to each other. respecting the line of feed.

The object of the invention is to provide a machlne capableof sewing at one operation a number of parallel rows of stitches and at the same time provide means forsecuring the needles in proper relation to each otherupon the needle bar, toprevent the points-being deflected laterally to spoil or render uneven the line of stitching, and to prevent the needles after passing down through the material, from getting into the path of the loopers.

-My invention, therefore, consists inthe,

matters hereinafter described and referred toin the appended claims.

My invention is illustrated in the accent-- panying drawings in which- Figure 1 1s a perspective view of my invention showing the arrangement of needles, the

guide foot, and throat plate. Fig. 2 is a perspective looking from the left hand of .the operator the work plate being removed. Fig.

. 3 is a detail view of the needle guard. Fig. 4

is a view similar to Fig. 2 but taken from'the.

plate.

opposite side. Fig.- 5 is a detail-of the throat Figs. 6, 7, 8, 9 and 10, show different forms of stitching which my machine is capabio of making.

In the drawings have only shown those parts of a sewing machine essential to prop erly illustrate my invention, the main actu- 'sewing machines, a type of which may be seen in Patent No. 344,493 of June 29, 1886.

In the drawingsA represents the needle bar, A the connecting rod through which motion is transmitted to the loopers D E, and X a portion of the bed plate. v

a, a a a. are the needles, shown in Figs. 1, 2, 4'and S as arranged in two sets of two each, the needles of each set being arranged so that a line connecting the needles of each set would beexactly at right angles to the line of feed, but a line connecting the two'sets of needles would be oblique-to the-line of'feed.

needle bar by means of a' double needle clamp bar at the right of the center or front of the bar, by the piece I), and the other two at the left or rear of the bar by the piece h The particular means for securing each set cember 24, 1889, to LfMuther. Furthermore,

I do not wish to restrict myself to the number of needles in each set.

In the use of two or more sets ofv diagonally means for guiding the points of the needles down to the, material, that is to prevent their deflection before they reach "the material. For thispurpose I have devised the form of needle'guide foot shown in Figs. 2and4 and marked F. This guide foot F is used in contherewitli .but in its lowest position either does not hear at all on the material beneath it, or, but very lightly. -The shank of this foot F is removably attached to the main presser foot bar Billy a set screw (1.

arranged needles it is necessary to provide junction with the ordinary roller presser foot. F, though other than a roller foot may be used. 11; isso arranged with respect-to the foot F that it moves up or down innnison In order to properly guide the needles to the material and prevent their deflection said These needles are prferably securedto the I p .B, two needles being secured to the needle,

of'needles in place is substantially the same as shown in. Patent No. 418,049, granted De-- ward movement, this slot being herein shown as arranged toward the rear of the foot andv out out of the side thereof. It will be seen by this construction of foot, proper guiding means are provided for the diagonally arranged sets of needles, there being a solid mass between the sets of needles.

In Fig. 5 in detail and in Fig. 1 -in opera tive connection with the other parts is shown the throat plate G. r This is attached in the usual way to the work plate, has the longitudinal opening for the feed and is provided with two openings 9' g set diagonally to each other respecting the line of feed to receive the needles arranged in the manner hereinbefore described.

Asa further and special improvement in bed of the machine beneath the throat plate '0 passes the other set.

in such position as v to prevent the needles springing into the way of the loopers D and E, when the latter are moving forward to take the threads from the needles. Thisis shown at C in Figs. 2, 3and 4. It is seouredto the bed of the machine below .the throat plate by two screws h, h, and extends into the direction of the length of the machine into the path of the needles beingprovided at'its outer end with two prongs a, 0 In the-speechetween these prongs o and 0 passes one set of needles a a and upon the outside of prong These prongs extending across the line of feed and at right angles thereto, or in the same direction as the -loopers guide the needles below the throat plate, preventing their springing into the way of the loopers D, E.

In orderto more accurately guide thence.

dies I have ohamfered the inner side of the prong c and both sides of the prong cjand in connection with the latt'er I provide a move able guard finger 6' moving in unison with the loopers; the needles a a passing on the outside of the prong c and between it and the linger e','the latter acting to contact with the needles attheir opposite side just before the looper is to enter the loop of the needle thread the said linger acting not only to do fleet the needle into the proper position with relation to the point of the advancing looper,

but also to aid in throwing out tbe loop of thread from the eye of the needle so as to be entered by the point of the looper, being the same as shown in Patent No. 434,096 to All;

Sawtell, dated August 26; 1890.

I am aware that stationary needle guards are old as are also needle guide feet and scenes ot' thestitchiug as regards number and distauce apart of the rows but by having the needle guide foot arranged as shown bending of the needles transversely to the line of feed. is prevented, and by the arrangement'of the needle guard, bending in the direction of the feed and consequent danger of springing into the path of the loopers are prevented.

Various other advantages attend the use of my inventionwhich willbe readily apparent.

It will be seen that by my construction'the needles may be arranged in sets, two in one set and one in the other, or in any other desired way for varying the number and appearance of the rows of stitching. See for example Figs. 6 to 10 inclusive.

, Having thus described my invention, what I claim, and desire to secure by Letters Patent,

In a sewing machine and in combination with the sets of needles arranged diagonally to the line of feed, and means foroperating the same, a pres'ser foonan independent needle guide foot having a slot in its forward end through which one set of needles passes and having a slot in the rear and to one side of the'fo'rward slot, and a needle guard arranged below the throat plate; substantially as described. I

2. In a sewing machine and in combination with'a pluralityof sets of needles and means for operating them, a needle guard arranged below the throat plate having a double pronged end and having a longitudinal slot between the prongs through which one set ofneedles passes and a guard located adjacentto and beyondtheouter. prong between which and the outer prong the second set of needles foot, a throat plate and a needle guard secured at one end to the bed'o'f the machine and extending transversely across thel-ine of feed having a lohgitudinal slot in its end- 'thereby forming two prongs between which one set of needles passes, suitable loopors D, E, and a guard finger-moving therewith adjacent to one of the prongs of the needle guard, the second set of noodles passing down through the space between the guard finger and the latter prong, both said prongs being chamfered; substantially. as described.

In a sewing machine, the combination with the diagonally arranged sets of needles, means for operating said needles,-the throat plate and loopers, of a needle guard arranged below the throat; plate and having a double in testimony whereof Iafix my signature in pronged end, between which prongs one set presence of we Witnesses.
